Hello,
is there a way to have a newly created item inserted in a different element
than the one the user clicked on? I tried out the children-feature, but I
do not get any features of this element's childs...
Here are the two situations. I'll model the containment structure and
annotate what item has to be clicked on and where the new item shall be
inserted.
a)
Subprocess <- click here
+-EmbeddedSubprocessAttributeSet
+-GraphicalElements <- insert here
b)
Pool
+-Process (unique)
+-GraphicalElements <- insert here
+-Lane <-click here

Ok, so I'd have to create a pseudo-containment-feature for the Class I want
to click on, so the right editParts and polcies are created. Later, the
pseudo-containment-feature would has to be removed again (or just ignored).
I took a look at the CompartmentItemSemanticEditPolicy. There a constant is
used to specify where to put stuff in (similar to the gmpmap). I doubt that
I can What method do I have to override to specify where to put it, when it
is not a feature of the class itself [1]? Execute? And could you point out
or send me a reference where else I would have to make changes, like for
moving or deleting the created element?
Thanks,
Tobias
[1] As I said: I want to click on a "Lane" and insert the new Element in the
collection Lane.getParentPool().getProcess().getGraphicalElements()

Right, XXXItemSemanticEditPolicy is the place to fix.
1. req.setContainmentFeature() is self-description. put correct metafeature
here (Pool_Process i suspect)
2. CreateXXXCommand - modify getEClassToEdit to point to owner of
containment feature from (1).
3. Fix getElementToEdit() method - navigate to the appropriate element (e.g.
Lane.getParentPool())
These midifications control only changes in the domain model, placement of
grapical elements should happen according to addChildVisual() logic in
appropriate edit parts.
As for move and delete, there should be no additional efforts (container
element is known at the time of removal)

Thanks, it works well for creation and delition, but when I move an element
it is reinserted in the pseudoElements-Feature (which is bad...). I think
I'll just keep my eyes open for occurances of the pseudoElements-Feature
and sooner or later I'll find the place to edit - but if anyone already
knows, please tell me! *g*

By the way, I mentioned a kinda strange behaviour of the generator: Most of
my elements can be inserted in two containers, which, as we all know,
results in duplicate EditParts for these features. However, when I
generated the editor with the ChildReferences contained in the second
container while the original EditParts already existed the duplicates where
not generated. When I deleted and recreated the whole editor (to get rid of
junk code from former configurations) the duplicates where there again.
So maybe you can generally avoid the duplicates by creating the editor with
only the originals in the gmfmap, then pasting the reference-children in
the map and recreating the code.
